Really wow. I knew NBC generally geo-blocked their affiliates. Wasnt aware the others have caught on. But it could be just the OKC affiliates.

I think it's mostly the groups that take the decision, rather than it being a network/affiliate issue.

I've found TEGNA stations have mostly been blocked since early this year, Tribune took theirs off around the same time.
It's the whole sites thater are blocked, not just the stream.
I find smaller marked independents and groups like Cox (and Sinclair) are still fine, for now.
